Biodiversity offsets

The Park Killesberg serves as the green centre of the newly constructed district in Stuttgart and continues the long history of the area as a garden show site with a contemporary expression of landscape architecture and as a model for interconnected green spaces. The design is the result of a collaborative process with the local authorities, citizens and neighbours (1).

Most of the open spaces around Munich are designated as green belt areas and are being used mostly for agricultural purposes. As a lead project of its green strategy, the city now aims to protect these areas and to upgrade their quality by cooperating with local farmers and promoting a shift to extensive and ecological farming, developing habitats, corridors as well as a network of cycle tracks and footpaths for recreation (Reference 3, 4). The city supports the farmers with advisory services, but also with the organization of the implementation of the ecological projects. The farmers are motivated to join by being able to use labels such as "Potatoes from the Greenbelt of Munich" on their products. (Reference 3) The initiative also includes herb gardens, provided by farmers and rented by citizens. (Reference 1) A further project included in the initiative is the "Münchner Ökokonto, a biodiversity offsetting principle by which the former low moor complex of the West of Munich is being renaturalized on 28 areas with a total area of 67 ha. (Reference 5)

Coal mining in the Dearne Valley damaged the Dearne Valley landscape. To address these problems the Dearne Valley Green Heart partnership was formed in 2006, but the intervention discussed here is specifically related to the developments between 2012 and 2015, when it was founded as a Nature Improvement Area. It is part of the South Yorkshire Delivery Programme and part of the Doncaster Council as also being part of the Doncaster Green Infrastructure Strategy (Ref 1, 2).

Hailes Quarry Park (HQP) is a large open space in the south-west of Edinburgh. It covers an area of 12.15ha. HQP was a very boggy area in the centre of the park which was effectively out of use. A project was planned which aimed to make environmental improvements and engage the local community and encourage healthy living. One of the main features of the park’s recent development is the creation of a wetland area with a range of wetland plant species. This new habitat will be home to birds, amphibians and native wetland plants, and will be a part of the green corridor. Additionally, a Biodiversity enhancement project was carried out at the site (ref 1, 7).

The Forest of Belfast is an imaginative label for urban tree initiative launched in the 1990s with the aim of conserving and managing existing trees, increasing the planting of suitable trees, particularly in places of public access like parks, and in promoting an interest in and an appreciation of trees and forestry(Ref 3). The project was officially launched in June 1992 (Ref 1). It is active throughout the urban area of Greater Belfast, including Belfast City. It brings together partners from the statutory sector, voluntary groups, businesses, and individual residents who become volunteer Tree Wardens. It shows how urban forestry can forge partnerships between central and local government, environmental organizations and city dwellers. (Ref 1). Forest of Belfast initiative was wound up towards the end of 2010 (Ref 6).

The Biffa Award awarded the Yorkshire Wildlife Trust with £24,681 in December 2013 for their ‘Lapwings on your Doorstep’ project, which started a number of habitat management activities at Potteric Carr Nature Reserve aiming to benefit a range of species. The project's main objective was to improve breeding conditions for the bird. Workers at the site, near Doncaster reported the scheme would
 also benefit a wider range of species, both common and rare, including other birds, bats and insects. It will also increase the reserve's value as an important tourist attraction, boosting the local city's economy. (Ref 1, 7).

The WWF Oasis of Valle Averto extends to the edge of the Venetian lagoon and is a typical fishing valley of the Venetian lagoon, the only one closed to hunting. It is located within a Community Importance Site (SIC IT3250030). It is also a Special Protection Zone (SPP IT3250046). The area, about 200 hectares, includes ample mirrors of brackish water, canes, igrophilous forests, canals. After being purchased by WWF, plants of the planífico igrofilo forest kind were re-introduced: oak, black poplar, elm, ash and other typical species (1).

The lagoon has a great local significance for its biodiversity with the presence of certain species of rare birds regularly stationed in this area. Much of the biotope was degraded in the last decade by systematic embankments, constructions, as well as the inconvenience caused by various man-made pressures. A project was developed to reconstruct the area within the framework of a collaboration of the Institute of Marine Biological Resources, Inland Waters of HCMR, and Hellenic Ornology Company. The project offers directions for completing a protected region and proposes specific projects and actions of scientific monitoring, ecological rehabilitation, regeneration, and promotion. (Ref 3)

The botanical garden of Athens was reconstructed in 2004 to protect and maintain the biodiversity of the area. Covering a land of 1,860 sq.m., this Botanical Garden hosts over 2,500 different kinds of plants from all over the world and a rich variety of flora. All the plants and trees are protected in the park. The community also sends seeds all over the country to spread and maintain biodiversity throughout the region and hold agroecological events to increase the concern and educate the locals (Ref 1,3). The park also has a lake and a library inside it. (Ref 2)

The Green Bridge at the D2 motorway in Moravian Svätý Ján (Dúbrava locality) is a project under the Alpine Carpathian Corridor Project (ERDF). The project deals with biodiversity and is focused on building a safe and efficient passage for migrating animals over the D2 motorway connecting Bratislava and Brno (Czech Republic). The mountain ranges of the Alps and the Carpathians, which straddle the border of Austria and Slovakia, are the largest sources of biodiversity in Central Europe. The Corridor’s structure has created a forum for the managers of these regions to share ideas and develop solutions that can be applied within the entire region, instead of only per protected area. To ensure long-term continuity, key stakeholders are party to a Memorandum of Understanding that can contribute to sustainability in their area of responsibility. (1, 5, 6)
